well, do some googling ("x remote program") to start off with. not to be
rude, but this is very standard stuff and there are hundreds of howtos
out there. that being said, heres what you want to be aware of:

*) the old way of authorizing xclients to connect to an xserver was via
xhost. dont use that method, its very insecure.

*) instead tunnel everything through ssh
   i turn that on by default for my ssh server:

   $ grep X11Forwarding /etc/ssh/sshd_config
   X11Forwarding yes
   (restart the server for this to take affect,
    /etc/init.d/ssh restart)

   and for the client:

   $ grep ForwardX11 /etc/ssh/ssh_config
   ForwardX11 yes
   ForwardX11Trusted yes

*) or use xauth
